SPECIFICATION forming part of Letters Patent No. 788,514, dated May 2, 1905.

Application filed October 26, 1904. Serial No- 230,088.

To all whom it vita/y concern.-

Be it known that I, SoLoMoN BOYER, a citizen of the United States, residing at Gentryville, in the county of Spencer and State of Indiana, have invented certain new and useful Improvements in Plows, of which the following is a specification.

In operating the chilled plow as generally constructed expense, trouble, and vexation are experienced by reason of the point becoming displaced or broken. This is due largely to the fastenings of the moldboard becoming loose and the moldboard working down and displacing the point. The plow points in common use have a shoulder at the inner or lower side to abut against the toe of the standard and are held to the latter by a single bolt. In operation the fastenings of the moldboard frequently become loose, and as a result the moldboard is borne downward and, pressing upon the plow-point, causes the shoulder to leave the standard, and the whole strain being thrown upon the point approximately in line with the fastening results in its breakage or straining of the parts. so as not unfrequently to require material repairs at the expense of time and money.

The invention is applicable to all kinds of plowsright or left hand, chilled-steel, sulky, gang, walking, or the likeand is particularly intended for all types of chilled plows.

The invention consists of a lug upon the inner side of the moldboard near its lower rear corner to engage over a rear extension of the standard.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawings.

While the invention may be adapted to different forms and conditions by changes in the structure and minor details without departing from the spirit or essential features thereof, still the preferred embodiment thereof is shown in the accompanying drawings, in which- I Figure 1 is a side view of a plow embodyis a detail transverse section showing more clearly the relation of the lug of the moldboard and the extension of the standard.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The plow-standard 1 is provided at its lower end with a wingto support the point 2 and 'moldboard 3, both being secured thereto in the usual manner. The rear extension 4 is straight upon its upper edge and is a trifle longer than shown in standards specially constructed with a View to secure the best results accruing from the invention.

The moldboard 3 has a lug 5 upon its rear side near its lower rear corner. This ing is preferably a part of the moldboard or may be welded or attached thereto in any determinate way. The purpose of the ing 5 is to engage over the rear extension 4 and support the rear part of the moldboard and prevent it from exerting a downward pressure upon theplow-point 2 in the event of the fastenings connecting it with the standard becoming loose. The lug 5 also relieves the moldboard fastenings in a great measure of the strain usually sustained thereby when the plow is in operation. While it is preferred to have the meeting edges of' the lug 5 and rear extension 4 square, they may be of any construction to provide an interlocking joint of well known form, thereby preventing downward displacement of the moldboard even though its fastenings should become loosened to such an extent as under ordinary conditions to permit appreciable downward movement of said moldboard.

Having thus described the invention, what is claimed as new is 1. In a plow, the combination of a standard having a rear extension, and a moldboard having a lug upon the inner side of its lower rear corner portion to cooperate with the said rear extension and materially relieve the moldboard of strain and prevent movement 1 board in proper position, substantially as set of the mold board in the event of its fastenings forth. 10 becoming loose, substantially as set forth.
